I am trying to set up the same thing using only LTM (no APM at all). I have my internal Exchange deployed using iApp ver. 1.5.0.
A mailbox in the cloud is unable to get 'free/busy' details from an on-prim mailbox. However, an on-prim mailbox is getting 'free/busy' detail from the cloud.
I have tried the solution starting on page 75 of the Deployment Guide (Exchange Hybrid Autodiscover and free/busy lookups fail when APM is deployed) with no luck.
What else am I missing here?

Hey Jacob, If you are not doing APM then BIG-IP is not getting in the way from an authentication perspective at least and that iRule you mentioned should not be necessary. I have not heard of any issues with Exchange federation with O365 when APM is not being deployed as the traffic should flow from O365 through the BIG-IP to the exchange servers just fine. Have you opened a case with Microsoft as possibly there is some misconfiguration?

One note is possibly to look at if it is a certificate issue between O365 and BIG-IP as a valid trusted CA cert is required for that communication: https://technet.microsoft.com/en-us/library/hh563848(v=exchg.150).aspx

Thanks for the quick response, James.
No case with Microsoft yet as I am needing to fully rule out the F5 first. I am waiting on support to get back to me as well. Once I have their answer, I may be able to push for a ticket with Microsoft.
